I discus how to calculate numerical aperture here.
Then I discus resolution in terms of NA.
Microscope objectives have the NA clearly marked, and the objective (along with the condenser) is what determines resolution. The eyepiece just magnifies, without improving resolution.

that not possible without knowing the numerical aperture?
